As an essential part of Multi-channel MAC protocol, the channel scheduling algorithm aims at enhancing the network throughput and resource utilization. Based on the WAVE standard in vehicular communications, this paper improves WAVE MAC by using the time division access on service channels and proposes a channel scheduling scheme to negotiate and allocate the channel resources for throughput-sensitive...
Based on the concept of random contention and collision resolution, a distributed QoS-guaranteed multiple access (QMA) protocol for mobile ad hoc networks is proposed to support multimedia service and multihop architecture. In the protocol, nodes with real-time traffic have higher priority to access channel than those with non-real-time traffic by broadcasting forecast bursts (FB) in earlier group...
Based on the concept of random contention and collision resolution, a QoS-based multiple access (QMA) protocol for ad hoc networks is proposed to support multimedia service and multi-hop architecture. The traffic is divided into two groups with different requirements on delay, namely real-time traffic and data (or best effort) traffic. According to the protocol, nodes contend to access channel, and...
A QoS-based multiple access (QMA) protocol for multi-hop ad hoc networks is proposed. In this paper, the traffic is divided into real-time and non real-time traffic. According to the protocol, nodes with real-time traffic have higher priority to access channel than those with non real-time traffic by broadcasting forecast bursts (FB) in earlier contention slots. Meanwhile, traffic is scheduled according...
